Strings in Python

In Python, a String is an important data type which is a collection of characters. Strings are used to store and manipulate text data. In Python, strings are called immutable, which means that once a string is created, no changes can be made to it. Strings have great importance in Python because they are essential for working with text data in every programming language.

In Python, a string is a sequence of characters placed between single quotes (' ') or double quotes (" "). Python strings can also be defined with triple quotes (''' '' or """ """), which are used to define multi-line strings.

Strings in Python can be represented in various ways: Single-line, Multi-line, Unicode, and Raw strings.

Many operations can be performed on strings in Python. Some important operations are Concatenation (+), Repetition (*), Slicing, finding the Length (`len()`), changing case (`upper()`, `lower()`), Replacing (`replace()`), Splitting (`split()`), and Joining (`join()`).

They are immutable, support indexing and slicing, have Unicode support, and come with many built-in methods.
